100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

The city of Copenhagen European Green Capital 2014 is carrying out lab tests on hydrogen, electricity and biofuels for cars. By 2015, 85% of municipal passenger cars should be running on electricity or hydrogen. By 2025, the target is for 20-30% of all passenger cars in the city to use hydrogen, electricity or biofuels, with five hydrogen fuelling stations in the Greater Copenhagen area.
